The idea here is that these islands should be viewed as regions and not nations - we should reconfigure the space of British politics along regionalist lines. For some contemporary political philosophers, regionalism offers the possibility of a new counter-hegemonic political movement that could draw on a region’s political traditions in order to support forms of political action that could bypass the moribund political traditions of the modern nation state.
In this way, regionalism is necessarily an anti-systemic and counter neo-liberal form of politics: a post-Westphalian radicalism for postmodern times, that recognises the central importance of local traditions as a political counter-force that can be mobilised against neo-liberal forms of marketisation and the commodification of public goods.
Hence the politics of the left needs to be more than knee-jerk ‘anti-Toryism’. The key idea here is that regionalist decomposition of nations into semi-autonomous regions is not only culturally and economically possible, but was also in some way 'inevitable' given the political trajectory of the global economy. Regions no longer need nations in order to survive either materially or culturally.
What we need in the UK today is regional forms of political autonomy mediated via the ‘authentic political traditions’ of particular regions. Regionalism in this way functions in the service of ‘progressive cosmopolitanism’ rather than nationalist particularism
